The production of bean sprouts is not limited by the season, and the cycle is extremely short, the input is low, the output is high, the market prospect is broad, and the production is easy. First, sand bean sprouts: 1, the venue. Free rooms, plastic greenhouses, etc. can be used, requiring a low light environment in the production room (shed). 2, choose sand. Should use medium and fine grain sand; coarse sand due to poor water retention, generally should not be used. 3, choose beans. All varieties of beans can be used to produce green sprouts. The bean sprouts, which are generally produced from large-sized beans, are thick, and the bean sprouts produced from small-sized beans are elongated. On the market, green bean sprouts are more popular with slender shapes. 4, sowing. Generally, 3 kg of soybeans can be sown per square meter and 30 kg of bean sprouts can be produced. From sowing to harvesting, it takes 4-5 days in summer, 6-8 days in spring and autumn, and 10-15 days in winter. After the bean sprouts are harvested, the site can be reused, and sowing is done in a circular manner, ie sowing beans every day and harvesting every day. 5, management. The management of sand green sprouts is very limited. It is only necessary to use the sprayer or water bottle to sprinkle water as early as in the morning or evening. This is much less than normal rootless sprouts. 6, harvest. Harvesting standards: bean sprouts grow neatly, 15-18 cm long, white and tender stems, green petals, no cotyledons exposed, can be listed after harvest. Second, foam box production of bean sprouts: 1, box. The complete foam box height is 25 cm or more, and the common specification is 60 cm and 47 cm. A complete foam box can be cut from the middle with a small hacksaw blade or a thin knife and can be made into 2 boxes. The box cover is glued with a wide tape as the bottom of the box, and the foam box can be used repeatedly. If the daily production volume is 10 boxes, about 50 foam boxes will be prepared in the summer, 60-80 foam boxes will be prepared in the spring and fall, and more than 100 foam boxes will be prepared in the winter as standby cycles. 2, sowing. Requires beans to be new species with a shelf life of no more than 12 months. There is no need to lay sand in the bottom of the box. Ordinary specifications of the foam box can be broadcast soy beans 0.5 kg, producing more than 5 kg of bean sprouts. 3, management. Foam box production of bean sprouts with less water, easy management, pre-stack moisturizing germination boxes, post-opening green. In order to produce high bean sprouts, good appearance, and large bean sprouts, bean sprout growth hormone can be used flexibly during production. It usually takes about 1 week from sowing to harvesting. 4, harvest. The bean sprouts grow to about 15 centimeters in length, and can be harvested after they are full.
